(yeah, first post to the list in ages, and it's 'cos I need help.... )
I have an mdadm RAID-5 array with - you guessed it - 2 failed disks.
Well, somebody else had it and didn't monitor it; so now it's dead,
and has landed on my desk (the data is irreplaceable, of course).
Some dd_rescue'ing later, I have images of all the disks, 2 of them
with ~5-10% unreadable each. The good news is that the unreadable bits
mostly don't overlap, so I actually have N-1 good data for ~99% (maybe
all - still checking) of the array, and so it's at least theoretically
possible to reconstruct the whole thing.
Clearly, I need a tool that lets me nominate which-disk-is-dead for
different block ranges. I don't think mdadm will help, so does anybody
know of anything like this?
